Monthly Forecast for Hokkaido Entering Winter on a Large Scale. And the snowfall in Sapporo?
Today (26), the Sapporo District Meteorological Observatory announced a one-month forecast. This week, there are many days when it snows mainly on the Sea of Japan side, such as the temporary increase in snowfall to 23 cm at Horoka. It seems that the amount of snow will continue to increase from now on. I summarized the expected weather characteristics based on the latest one-month forecast.
Week 1 (November 28 to December 4) Snow and cold intensify
Today (26), the Sapporo District Meteorological Observatory announced the outlook for next month.
Starting tomorrow (27), the winter-type pressure distribution will continue and it will be easier for strong cold air to enter the sky. Especially from the 30th to the 1st, a cold air similar to midwinter will flow in the vicinity of 5500 meters above the sky, and there is a possibility that the snowfall will intensify mainly in the northern part of the Sea of Japan side. The beginning of December is likely to start with snow scraping off the side of the Sea of Japan in many places. The temperature is about the same as normal or slightly cooler, and it is expected that there will be a few days of midwinter. Be careful not to get sick, like wearing warm clothes. On the other hand, on the Pacific Ocean side and the Okhotsk Sea side, there are likely to be a lot of sunny days and sunny days.
After the second week (December 5-11) What about the snowfall in Sapporo?
The strength of the winter-type pressure distribution is typical and the temperature is expected to be approximately equal to normal. There are many cloudy and snowy days on the Sea of Japan side and the Sea of Okhotsk side, and it appears to be relatively sunny on the Pacific side. The long-term average snowfall year (root snow) in Sapporo is December 5, but for now, it is difficult for snow clouds to flow into central Sapporo, and it appears that even if the snow accumulates, it will melt. soon. Snowfall in Sapporo can be delayed compared to normal years.
3rd to 4th week (December 12 to 25) A winter production
During this period, the power of the high pressure on the mainland will increase, while the low pressure is likely to develop in the eastern part of Japan, thus the winter-type pressure distribution is expected to be slightly stronger. usual. Due to this effect, the Pacific Ocean side will have more sunny days as usual, but other than that, it is easy to snow mainly on the Sea of Japan side, and it seems that the amount of snow will increase. Even in Sapporo, it seems likely that it will be snowing within this period at the latest. Winter will surely approach on a large scale.
